Oil burner lights but then shuts down within a couple of minutes (video)
My oil burner is acting up and although it lights right up it isn't staying lit. There's also a weird crackling or clicking noise that you can hear in the video.
It isn't consistent though because last night I turned it on and it was on for over 2 hours, I turned it off and then turned it on again a short time later just to test it and at that point it turned on then turned off within a minute but the blower stays on so of course it's blowing cold basement air up into the house.
Money's tight so I don't want to call somebody in if I don't need to and I'm not afraid to fiddle around with things so I'd appreciate any guidance you guys might be able to give. Thanks so much!

Welcome to the forums.
It's hard to tell where that clicking is coming from. At the end of the video.... the burner shut down. Was that it going into fault and shutting down by itself ?
If yes... I noticed the oil burner LED was normal until the failure. That tells me that the oil burner itself is probably not the problem. That leaves the main air blower. What was it doing ? Did it shut down too or remain remain running when the burner shut down ?
I'm thinking the furnace overheated and shut down on over heat. Have you checked the filter ? Are you getting a good flow of air out of the registers when the blower is running ?
Lots of questions..... not an easy repair without actually being there.

Hi thank you so much for responding.
My first thought was the filter so I replaced that. The blower does stay on after the burner goes off so it blows the cold air from the basement up.
I almost feel like the clicking noise is coming from that silver box on the right-hand side which I assume is maybe electrical? I guess the only way to really know if that is what it is is to take that cover off so I may give that a shot in a bit. I guess what I don't understand is what in that could be causing the burner to shut down.

The furnace has a sensor that monitors the heat inside the heat exchanger. If it reaches a preset temperature.... the sensor shuts the burner down to keep the furnace from dangerously overheating.
A model number of the furnace would be helpful.

When the furnace shuts down do you have to reset it for it to come back on does it do it by itself. Is it shutting down on high limit or safety.
Does the blower eventually shut off by itself.
That clicking almost sound like you have a loose connection somewhere. Did you check all the connections on the control.
If you open that box with the power off you can check to see if all connection are tight in there also if you have any.

That looks to be a Rheem product.
There are two possibly three limit control switches in that model. They interrupt the burner... not the blower.... in case of overheat. This overheat is caused by lack of or reduced airflow thru the furnace. It could also be caused by a sooted up furnace. When was the last time the heat exchanger was taken apart an cleaned ?
